Rescuing John - Inside Nergal's Lair- Nergal/Zee/X-23
As concerned as she was for Laura's well being, Zee had gotten the sense that the woman was every inch the strong fighter she seemed. Strong enough that she could handle the demon for a time while she made life difficult for any of Nergal's servants to get to them. The question was how was she going to manage that without trapping them all with him. Hopefully, she wouldn't exhaust herself, or at the very least Loki would be listening like they said he would and could portal them out. She just hoped he was as attentive as he seemed.
When Nergal rushed Laura she took a step back and held out her hands, taking a breath before she called upon her magic again. "Raeh em senotsgalf, esir morf ruoy ecalp dna gard eht htrae fo lleh htiw uoy. Hcuot eht gniliec dna peek tuo lla taht dluow emoc resolc." As the last of her words left her lips the whole of Nergal's lair rumbled loudly and noticeably shook before a section of the floor a few feet behind Nergal began to rise, blocking off the end of the corridor with a resounding thud when it smashed into the ceiling.
It wouldn't hold forever, especially if Nergal had summoned the whole of his army to the other side, but it should be long enough for them to deal with the demons and hopefully get out alive.
